DN Series
IEC sizes = 63 ÷ 180
Nominal power Pn= 0.18/0.12 ÷ 22/18.5 kW
Polarity = 2/4, 2/6, 2/8, 4/6, 4/8, 6/8
Energy efficiency= IE1
Nominal torque Mn= 0.60/.060 ÷ 99.7/131.4 Nm
Rotation speed n = 850/660 ÷ 2930/1460 rpm
The DN series motors are three-phase motors with single polarity that allow using two different speeds depending on the connections applied.
The double speed DN motors can be made:
- with single three-phase winding with DAHLANDER/YY configuration (single winding) for motors equipped with double polar couples (2/4 and 4/8).
- with double three-phase internal winding for motors with polar couples 2/6, 2/8, 4/6 and 6/8.
Double polarity motors can be supplied with following polar couples:
| POLAR COUPLES | ROTATION SPEED [rpm] |
| 2/4 | 3000/1500 |
| 2/6 | 3000/1000 |
| 2/8 | 3000/750 |
| 4/6 | 1500/1000 |
| 4/8 | 1500/750 |
| 6/8 | 1000/750 |
These motors are available with B3, B5 and B14 flange and have following characteristics:
- IEC sizes = 63 ÷ 180
- Nominal power Pn= 0.18/0.12 ÷ 22/18.5 kW
- Energy efficiency= IE1
- Nominal torque Mn= 0.60/.060 ÷ 99.7/131.4 Nm
On specific customer request M.T. Motori Elettrici can supply triple speed motors, supported by its technical department.
All M.T. Motori Elettrici motors are manufactured complying with IEC international standards.
